Note1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are
measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead =
1/18” from the package.
Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the
input/output differentially and the output current. Guaranteed maximum power dissipation will not be available over the full
input/output range.
Note3: Quiescent current is defined as the minimum output current that requires maintaining regulation. At 12V input/output differential
the device is guaranteed to regulate if the output current is greater than 10mA.
Note4: Vout1 and Vout2 are connected to the PCB cupper area 5.5mm*5.5mm separately. If you need large PD or lower Tc & Tj,
please connect to the large cupper area >> 5.5mm*5.5mm (like 10mm*10mm).
